Update (4 p.m.): Apparently, Brady had all of his procedures done in California with family doctors, which was against the team’s suggestion to go with hand-picked doctors from Boston. As a result, the Patriots are unhappy with the situation, especially if it adds a few MONTHS onto his rehabilitation time.

According to the Boston Herald, doctors have been working aggressively to fight an infection in Tom Brady’s surgically repaired knee. In fact, they have performed three procedures to try to eliminate the infection entirely.

The fear apparently is that the pattelar tendon graft (used to replace Brady’s torn ACL) is “in danger of becoming comprimised.” In that scenario, Brady would need to undergo a new ACL procedure, which would reset his rehabilitation clock.

Bill Belichick better feel comfortable with Matt Cassel, because it appears Tom Brady may not be ready by the beginning of the 2009 season. Ideally, this is just an overblown report and his infection will improve. This story certainly bears watching…
